Reflexology is a scientific art based on the premise that there are zones and reflex areas in the feet, hands and ears that correspond to all body parts. Each specific point corresponds with an internal organ, gland and other structure. Reflexology is administered by using the application of thumb and finger pressure to specific points on the feet, hands or ears. The pressure allows the release of blocked energy and built up toxins. During a treatment, mental and physical tensions are released and a state of relaxation is induced. This allows the body to: improve circulation; encourage lymphatic drainage and toxin buildup to release; stimulate nerve pathways; and relax muscles. A scientific explanation of reflexology is that the pressure sends signals that balance the nervous system, stimulate the lymphatic system (to drain the body of toxins) and/or release chemicals, such as endorphins, that reduce pain and stress. Foot reflexology is the most common type of reflexology because the feet are the final destination for over 7,000 nerve endings that are connected to every organ, body part and gland in your body. Through your feet, there is the opportunity to reach almost every part of your body. Reflexology works best when it is used for prevention or as a complementary therapy. A study in the American Cancer Society journal found that one-third of cancer patients used reflexology as a complementary therapy. Studies also show that reflexology may have benefits in palliative care of people with cancer.
